WHEEL PLQW.

SPECIFICATION forming part of Letters Patent N 0. 473,803, dated April 26, 1892.

Application filed February 5, 1892. Serial N0.420.462- (No model.)

To all whom it may concern:

Be it known that we, EDMUND C. \VESTER- VELT and CHARLES WV. OLAPP, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvementsin Wheeled Plows and we doherebydeclare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure 1 is a side elevation of our improved wheel-plow, looking at the landside. Fig. 2 is a top plan view thereof. Fig. 3 is a detail view showing the furrow-wheel mountings. Fig. 4 is a detail view of the front-wheel mountings. Fig. 5 is a detail rear view of the plow.

This invention is an improvement in wheelplows, its objects being to provide improved attachments whereby an ordinary plow can be mounted on wheels, so that it can be easily transported, and whereby the depth of the furrows cut thereby can be regulated at the will of the plowman or driver.

The invention therefore consists in the novel constructions of the mountings of the several wheels and in the novel combinations of parts, as are hereinafter clearly specified and claimed.

In the drawings, letter A designates the plow-beam, and a the plow, of ordinary construction.

B designates a tubular casting resting upon the front end of the beam, having a depending and projecting flange B, the inner face of which is rounded or rocker-shaped and bears against the side of beam, and is secured thereto by bolts 12 Z) in its ends, as shown. By loosening one bolt and taking up the other the casting can be shifted or turned on the beam, as is evident, and then by tightening both bolts it will be firmly held in such position. The front wheel 0 is mounted onadouble-eranked axle c, which is journaled in casting B, as shown, and by adjusting this casting, as described, any amountof gather may be given the front wheel by causing it to stand at an angle to the beam. The shaftc maybe rocked by means of a crank-arm 0, connected by pitman (Z to a lever D, pivoted to the beam above the plow, and having a hand-latch engaging a sector fixed to the beam, by which means the front wheel may be adjusted vertically, so as to elevate or depress the front end of beam.

E designates a bracket fixed to or cast on the rear part of the beam, and in it is journaled a stub rock-shaft F, to one end of which is fixed a lever F, provided with a hand-latch engaging a toothed sector 6 on bracket E.

G designate a landside-wheel journaled on a stub-shaft gin the lower end of yoke 9 which is rigidly connected to the shaft F, so that by rocking this shaft the landside-wheel is swung vertically, and thereby raised or lowered and can be held at any point.

II designatesa metal bar attached to the beam and projecting horizontally from the furrow side thereof, just in advance of the plow, and braced by rods h or in other suitable manner.

I designates a cranked shaft, one end of which is journaled in bearings formed on or secured to outer end of the bar II, and on the lower end of said shaft is journaled the landwheel *6. j

J is a lever loosely mounted on the shaft near the end of bar H and having a handlatch engaging a toothed sector H on the end of said bar. This lever has a short horizontal arm j, projecting rearwardly and loosely engaging a slot is in the upper end of a linkplate K, the lower end of which is strung on the aXle 0 near the hub of Wheel 2'. A spring K is interposed between the bottom of slot 7.: and end of arm j, and should be stout enoughto hold arm j in the upper end of the slot, so as to keep the hub of wheel iseparated as far as possible from the end of arm j. By this construction when lever J is adjusted it shifts shaft I through link K correspondingly, thereby shifting thelland-wheel, and when the plow is in operation if wheel 2' strikes an obstruction, forcing it backward, the shaft II will swing backward, causing the compression of spring K, but, however, relieving strain on the lever and not disturbing the plows'hare, thereby enabling the plow to cut furrows of more nearly regular depth in irregular stony ground than could be done if the wheel J were rigidly locked to the beam. In other words, t will be seen that we have a cushioned, yielding, and self-adjusting connection between the land-wheel and beam. A drivers seat may be put on the beam'or bar H in a position where the occupant can easily manipulate all the levers and thereby have the plow entirely under his control.

Having described our invention, what we claim as new, and desire to secure by Letters Patent thereon, is-

1. The combination, with the plow-beam, of the casting having a rounded face bearing against the side of beam, the bolts for securng and adjusting said casting, and the rocking crank-shaft connected to said casting and adjusted therewith, means for rocking said shaft, and the wheel thereon,substantially as described.

2. The combination, with the plow-beam, of the tubular casting havinga depending flange rounded on its inner face and bearing against the side of the beam, the bolts in the ends of said flange connecting the same adj ustably to the beam, the crank-shaftjournaled in said casting, the wheel thereon, and the devices for adjusting said crank-shaft, substantially as described.

3. The combination of the beam, the bracket on the rear thereof, the horizontal stub rockshaft j on rnaled therein, and the sector on said bracket, with the Vertically-swinging yoke connected to said rock-shaft, the wheel carried thereby, and the lever connected to said rock-shaft for adjusting said yoke, substan: tially as described.

4:- The combination of the bar, the cranked shaft jonrnaled thereon, the wheel on the lower end of said shaft, the armed lever pivoted above the wheel, and the plate loosely connected to the shaft beside the Wheel, and the yielding spring-controlled connection between the upper end of said plate and the arm of lever, substantially as described.

5. The combination of the beam, the'bar connected thereto, the crank-shaft journaled on the extremity of said bar, the wheel on the lower end thereof, the lever loosely pivoted on the shaft above the wheel, the plate loosely con nected to the shaft beside the wheel and having its upper end slotted and engaged by an arm on the lower end of the lever, and the spring interposed between the plate and said arm, and means for adjusting and locking said lever, substantially as described.

In testimony that we claim the foregoing as our own we affix our signatures in presence of two witnesses.
